  17. Set your location as London, this sets the timezone for the computer.

    18.  
  18. Fill in your details to create a new account on the Linux computer. For the password I used Pa55word. You should make sure you set a password that you can remember.

    19.  
  19. Once the installation has finished click the nine dots at the bottom left and type in terminal.

    20.  
  20. You should be left with a terminal as shown below. This will let you enter various Unix commands.

    21.  
    Learning Linux
  21. Many of the commands in Linux are very terse and initially seem to be not particularly intuitive. You might need some time to become accustomed to them and perhaps a little longer still to appreciate their great power. One of the most useful commands is man. It gives the man(ual) pages for specified commands.
    • pwd
    • ls
    • cd
    • mkdir
    • cp
    • mv
    • rm
    • rmdir
    • cat
    • more
    • less
    • df
    • du
    • wc
    • sort
    • diff
    • find
    • whereis
    • nslookup
    • man

    Look at the man pages for these commands by typing man then the command in a terminal window e.g. man pwd (use the space bar to scroll down, q to quit). Make brief notes. Explain the difference between more and less
